🔷Relationship between Glaucoma and Retinal vein occlusion🔷
🔶Clinical Case Series🔶
🔴Clinical Case:
Patient with superior hemiretinal vein occlusion and open-angle glaucoma.
🟢 Retinal vein occlusion (RVO), a sight-threatening disorder, is recognized as the second morbidity in microvascular disease, such as retinopathy. It is generally classified as central retinal vein occlusion (CRVO) or branch retinal vein occlusion (BRVO) (Becker & Post 1951).
🟢 In addition, when the superior or inferior half of the retina is involved in RVO, it is referred to as hemiretinal vein occlusion (HRVO) (Hayreh & Hayreh 1980).
🟢 Retinal vein occlusion (RVO) is associated with older age, symptomatic ischemic heart disease, higher systolic blood pressure and uncontrolled hypertension; however, the relationship between glaucoma and RVO is a topic of heated controversy.
🟢 Traditionally, a close relationship between VOR and glaucoma has been emphasized. On the one hand, it is well known that RVO can increase the potential development of neovascular glaucoma (NVG) (Calugaru & Calugaru 2013).
🟢 The development of NVG in CRVO, HRVO and BRVO is a serious and well-established complication, particularly in the CRVO (Beaumont & Kang 2002a; An & Kwon 2013).
🟢 On the other hand, glaucoma is a known risk factor of VOR, as shown in many previous studies (Mitchell et al. 1996; Sperduto et al. 1998). An increased risk of BRVO and CRVO has been found in patients with a history of glaucoma. An intimate association has been affirmed between open-angle glaucoma (OAG) and RVO (EDCCS 1993; EDCCS 1996).
🟢 However, more and more researchers have denied the accelerated effect of glaucoma in RVO risk. Some population-based studies have suggested that glaucoma is not related to VOR prevalence (Johnston et al. 1985; Klein et al. 2000; Jonas et al. 2013; Zhou et al. 2013).
